REFRIGERATOR-LINING.

Specification of Letters Patent.

Patented May 1, 1917.

Application filed March 28, 1914. Serial No. 828,078.

To all whom it may concern.-

Be it known that I, CHARLES TETTENBORN, residing at Cincinnati, Hamilton county, State of Ohio, have invented certain new and useful Improvements in Refrigerator-Linings, of which the following is a clear, full, and exact description, attention being called to the drawing which accompanies this application and forms a part thereof.

This invention concerns an article of manufacture which enters into the construction of refrigerators and serves as a lining for the chambers and compartments thereof. Such linings are made of various materials and my invention concerns more particularly linings which are made of mineral matter, such as is involved in, or similar to that used in the manufacture of glazed earthenware, pottery ware, porcelain, etc.

One or more of such linings may be used in a particular style of refrigerator, this being dependent on the size of the refrigerator, its purpose and special requirements.

Such linings are used in connection with an inclosure, the walls of which and the linings mentioned, are fitted to each other, reservation being made for insulating space between them and where more than one lining is used they are also fitted to each other so as to produce in conjunction with the inclosure a compact structure.

The invention consists of the construction of such linings as hereinafter described and claimed and as illustrated in the accompanying drawing in which:

Figure 1. shows such a lining in frontelevation.

Fig. 2. is a horizontal section through the upper part thereof.

Fig. 3. is a similar section through the lower part thereof.

Fig. 4. shows a detail of construction by means of an enlarged vertical section which is taken on line H of Fig. 8.

Fig. 5. in a View similar to Fig. 1, shows a modified construction.

Refrigerators are divided in compartments, there being usually at least two of them, one below the other, one to receive the ice and the other serving as a chamber which receives food and provisions. Where there are additional provision chambers they may be below the ice-chamber or to the side thereof.

These compartments are open. on one side, which is usually the front side in refrigerators of the type here under consideration. Doors are provided to close this open side. The other sides are lined with various materials suitable for the purpose.

In some kinds of refrigerators these linings are made of glazed earthenware, such as pottery-ware or porcelain and are integrally connected to form a self-contained structure. These structures are fitted to each other and to a suitable inclosure with insulating material interposed between. Structures of this kind are here under consideration.

In the drawing, letter A indicates ice compartments and letter B indicates provision compartments. These compartments may be contained in independent structures, or one structure may be subdivided to form a plurality of compartments. In the drawing, Fig. 1, shows a structure so subdivided by an integral partition D, the compartment above this partition forming an ice compartment and the one below thereof forming a provision compartment. Fig. 5, on the right, shows a structure subdivided in a similar manner.

Numerals 8 and 9 indicate respectively top and bottom of these structures. 10-10 are the sides thereof and 11 indicates the back of each. The ice is supported above partition D in any suitable manner and cold air is admitted to the compartment below through an opening 12. Water resulting from the melting ice is permitted to drain through an opening 13 and the upper side of partition D may slightly slope toward this opening.

An integral marginal curb 14: is provided at the front edge of partition D to prevent any water from passing over said edge. This curb is also extended along one edge of opening 12, as shown at 15, for the same purpose, and a hood 16 integral with the structure is provided above this opening to prevent any water from dripping through the same.

Circulation of air is rendered possible by permitting warmer air to pass out of the compartment below the ice compartment for which purpose an outlet opening 17 is provided. In the arrangement shown in Fig. 1, this opening is provided in partition D.

As shown in Fig. 5, it is provided in one of the sides 10,the one nearest the additional provision compartment, this latter having a similar opening 18 opposite opening 17. In the arrangement shown in this figure the circulation is completed by additional alined openings 19 and 21. e

Flue collars 22 are interposed in each case between the opposite openings. In the arrangement shown in Fig. 1, the circula-v tion is completed by a flue, the wall 23 of which is also integral with the structure, said flue'rising: from opening 17 and terminating below top 8. Water draining through" opening 13 is received by a tubular waste-duct F formed also integral with'the structure and'guided thereby toward an outlet'24c, providedwith a nipple 25 to permit fitting of a waste-pipe. This waste-duct is preferably open in front as shown at f in Figs; land 3, to'facilitate cleaning; At its upper end it has" a funnel-shaped enlargement to'mor'e readily catch'the Waste water and also any condensation which may form ontheunder' side of partition D and which is caused to drain toward the waste-duct by the slope'of' this underside. The upper edge of this'enlargement is spaced from this underside as shown at d to permit such drainage;

Outlet 24L is air-trapped by means of a body of'water held between a neck 26 and a somewhat'higher' curb '27, the outlet being closed by a cap 28, the lower edge of which dips intothe water. The cap rests upon neck 26 from which it is held spaced by means of lugs 29.

31' are ledges positioned opposite each other and provided integrally with the sides of the structure. They serve for the purpose'of supporting shelves.

Having described my invention, I claim as new:

1: A lining for refrigerators comprising a main body consisting of continuous vertical side and back walls and horizontal top and bottom walls and having an open front, an intermediate horizontal'partition dividing-such body into a food and a superposed ice compartment both accessible through said open front, said lining'ibeing provided adjacent to one of said vertical walls with a drain opening-,said last mentioned vertical wall being providedwith a pair of'later'ally projectingribs'formed integrally with said Wall and affording an open sided drain duct leadingdownwardly from said opening in the partition, said several walls and partition being formed of glazed earthenware inte'grally united into a unitary structure.

2. A lining for refrigerators comprising a main body'oonsisting of continuous vertical side andbackwalls and horizontal top and bottom walls and having an open'front, an intermediate horizontal partition dividing such body into a food and a superposed ice compartment both accessible through said open front, said lining being provided adjacent to one of said vertical vvlalls with a drain opening, the top and bottom faces of said. partition sloping downwardly toward said opening, said lEtSlI-H18Ilt10I16Cl vertical wall being provided with a pairgof laterally projecting ribs formed integrally with said wall and affording an open sided drain duct leading downwardly from said opening the partition, said ribs diverging ait'the'ir upper ends, and said severalwalls and partition being formed of glazed earthenware integrally united into a unitary structure.
